The Yamhill County Sheriff's Office is asking for the public's help in finding a man accused of raping a 25-year-old woman at a park near McMinnville last Saturday.

The woman was with her son at Edward Grenfell Park, about 4 miles west of McMinnville, when she was sexually assaulted by an 18- to 22-year-old stranger, said Captain Ken Summers, a sheriff's spokesman.

The suspect is described as 5-feet-8 with a medium build. He was clean-shaven and wore a shiny, green, polo-style soccer jersey, blue jeans and a white cowboy hat.

Investigators think he might be called "Alberto."

Two other men of about the same age were with the suspect before the rape occurred. They might be driving a light silver-green late 80's or early 90's Honda Accord.

Anyone with information is asked to contact Detective Rich Geist at 503-434-7508.
